One note, the perspective of the photos is a bit confusing. In most, the rug almost looks like it goes to the wall but in 1st one there looks like there is a lot of room. So it's kind of hard to know sizing and spatial relationships.

But, here are a couple thoughts:
The glass and black rect coffee table is kind of cold and impersonal. Something wood tone and/or oval or with some curve would help soften the room.

Electronic cords really bring a space down. Is there a way to hide them? You could set TV on a console and hide cords behind. Although the chair would no longer fit. If you keep a chair there make it more functional. Add a little table where you can set a cup of coffee while curling up with a book and occasionally enjoy the view outside. Right now, the chair is just an extra seat. Hopefully Beverly sees your post and can provide layout options. She is the best at it.

A tallish plant like a ficus or rubber tree etc would look good in a corner.

Mirror by entrance is small and unconnected to anything and doesn't reflect anything interesting. What is the pipe next to it? A stove pipe?

I'm also not a fan of the small side table by the couch. seems crammed in there though I understand why you have it. Maybe declutter it.

Your view is so pretty and relaxing you prob don't need window dressing unless privacy is an issue. The view is really the star of this room.

Some option

I would go with lower TV.
